- I think you'll find that MSCDEX is meaningless in the context of NT. NT
- has a set of SCSI device drivers for certain SCSI adapters; it can layer
- one of several filesystems including ISO9660 on top of the SCSI drive. MSCDEX
- is a filesystem translater and redirector for MS-DOS; it intercepts filesystem
- calls to specific drive letter and redirects them to a different
- filesystem (an implementation of ISO9660), and the filesystem calls a device
- driver. That's entirely an MS-DOS artifact and is probably irrelevant in the
- context of NT. For NT to be able to use the Soundblaster Pro non-SCSI CD-ROM
- interface, someone will have to write a driver for it specifically for NT.
- The fact that it's supported under MS-DOS with MSCDEX is pretty much
- irrelevant; what I was talking about in my previous message was that the
- interface is *not* SCSI, as the first message stated, and that NT is
- currently supporting CD-ROM drives over *SCSI* and then only over a few
- SCSI adapters. Expecting NT's SCSI drivers to work with the Soundblaster
- Pro's non-SCSI interface is a waste of time.
